I just bought a 2004 Scag TT with a 27 liquid cooled. The temp guage runs close to the red but not too close. I would say it is 80% into the green, or one red widths down from the red. Original owner said it has been like that since new. I noticed the coolant looked weak so I plan on changing that. I measured engine temp with my infrared thermometer. It runs 200-220 all over EXCEPT for the casting part at the very rear of the engine where the exhaust bracket bolts on, and that seems to run 450-500. Hoping that may be exhaust related and normal. How high does your guage run normally??? Thanks!!!
